Originally created for randomly selecting employees for drug testing,Random Clock# Generator has found many uses from drawings and lottos to classroom use.Because Random Clock# Generator randomly selects an item then removes it from the inbox,an item can't be selected twice(unless you reload the inbox).You can select the quantity you want to generate and RCG randomly selects this quantity from the inbox and moves them to the outbox where they can be viewed,printed or exported to Excel. Meets Dot Requirements.
